SPECIFICATION forming part of Letters Patent No. 710,087, dated September 30, 1902.

Application tiled October 15, 17.901. Serial No. 78,675. (No model.)

To @ZZ whom it Ina/y concern:

Be it known that we, WILLIAM W. TUCK, residing at Richmond Hill, and AUGUST WASSMANN, residing at Hallets Point, Astoria, Queens county, and State'of New York, citizens of the United States, have invented certain new and usefullmprovemen ts in Feed- Oontrollin g Mechanism for Hydrocarbon-Motors, of which the following is a specification suicient to enable others skilled inthe vart to which theinvention appertains to make and use the same.

Our improvements relate to mechanism for regulating and controlling the feed-supply of hydrocarbon fuel to motors of the class in which combustion of the vaporized hydrocarbon and the expansion ofthe gases generated thereby are utilized against a reciprocating piston.

The object of our invention is to render the feed-controllin g mechanism more delicate and sensitive in operation as well as more rapid and accurate in adjustment, and also to provide for its control by hand as well as by means of an automatic governor.

. The invention consists in thespecial arrangement of parts herein described and claimed, although we do not conne'ourselves to the identical structure shown, since various modifications and mechanical eXp'edients maybe resorted to without departing from the spirit and intent of our invention.

In the accompanying drawings, Figure l is an elevation showing the relation of our feedregulating mechanismV to a kerosene-engine. Fig. 2 is a horizontal section upon plane of line 22, Fig. l, showing a plan 'of the feedcontrolling mechanism and of the y-wheelupon which the centrifugal governor is situated. Fig. 3 is a sectional elevation, upon an enlarged scale, showing the feed mechanism thrown out of action. Fig. 3u is a detail section upon plane of line 3 3a, 3; Fig. 4, a view similar to Fig. 3, showing the feed mechanism adjusted to afford the maximum degree of feed. Fig. 5 is a view of the parts in the same position taken from the side opposite to-that shown in Fig. 4 and showing the governor and a portion of the iiy-wheel in elevation. Fig. 6 is an elevation taken at right angles to Fig. 4.

A represents the engine and vframework generally.

B is the crank-shaft, on which is situated a pinion meshing with two gears, as seen in Fig. l, one on each of the cam-shafts C C, said pinion and gears being within the casing, and therefore not shown. The cam-shafts are timed to rotate once for every two rotations of the crank-shaft B, so that their cams c c are brought into action during every second complete reciprocation of the piston, first acting upon the cross-head D,carrying the rods d d, by which the exhaust and air valves are opened, after which the cam c' comes in contact with the roller c upon the end of the inner arm e of the rock-lever E, the outer arm c2 of which acts indirectly upon the piston- I'od fof the oil-pump F through the medium of the controlling-slide G and follower H.

f is the supply-pipe for conducting kerosene or other hydrocarbon to the pump.

f2 is the feed-pipe connecting with the injector, by which the fuelisintroduced into the combustion-chamber in the usual and Wellknown manner. The follower H simply rests loosely upon the end ofl the pump-rod f, being held and'maintained in position by the bracket H, through which it passes.

The rod e3, upon which the contact-point e4 is formed, is adjustable upon the end of the outer arm c2 of the rock-lever E for the purpose'of setting said, point e4 accurately with relation to the controller-slide G. This may be accomplished, as shown in the drawings, by threading said rod c3 for engagement with anadjusting-nut e5 and lock-nut e6. The rockLlever E is fulcrumed on a stud i upon the eccentric I, boXed in the frame and having the lower end of the lever J secured to its opposite side. As a result the fulcrum of the lever E may be adjusted within certain limits with relation to the center of the camshaft C', thereby varying the stroke of the contact-point c4, as hereinafter set forth. A

coil-spring R, secured to a stationary part of the frame and to the inner arm e of the lever E, tends constantly to throw the outer arm e2 upward against a suitable stop a3.

The lever J is provided with a pawlj, which engages with the teeth upon the periphery of the segment K for the purpose of holding the shaft j and eccentric I positivelyin position.

The controlling-slide G is pivoted at its inner end to the lower arm m of the rock-lever M, pivotally supported upon the bracket a, in which the eccentric I is boxed. The other arm m/ carries a roller m2. A coil-spring m3, secured to the arm m at one extremity and to the stud 1l or other convenient pointof attachment at the other, tends constantly to throw the lower end of the arm m into contact. with the stop a upon the bracket at. A fiat metal spring g is secured to the under side of the controlling-slide G and extends backward over the stud a2, so that it tends constantly to press the controlling-slide G downward against the upper end of the follower H. The controller-slide G is formed with a recessg upon its upper side, into which the contact-point e4 enters when said slide is drawn inward sufficiently for the purpose of cutting off the oil-supply.

Upon the same stationary shaft yn. upon which the lever M is mounted is also fulcrumed the hand-lever P, the shorter arm p of which carries the roller p' for contact with the roller m2 upon the inner end m of the lever M when it is desired to adjust the controlling-slide G by hand. The lever P is provided with a hand-pawl )2 for engagement with the segmental rack C, attached to the segmental rack K or to otherl stationary support.

Upon the inner face of the [1y-wheel W is pivoted a tangential segment T, the motion of which is limited by a pin t, said tangential segment being drawn inward by a coil-spring S under normal conditions, but yielding under centrifugal force sufficiently to protrude into the path of the roller m2 upon the rocklever M whenever the speed of the engine is sufficiently great.

It will be seen that by our arrangement the controlling-slide Gis adapted to be regulated in position by hand as well as automatically by the governor. Thus by means of the hand-lever P and segmental rack K the roller p, acting on the roller m2 on the rocklever M, may be made to retract the controlling-slide G more or less against the resistance of the coiled `spring m3 to decrease or even cut off the supply ol'l oil, since the farther the pivotal point `or fulcruxn of the controlling-slide Gis retracted from the path of the contact-point e4 the less the thrust of the latter willdepress the pump-rod until the recess gis reached, when the stroke ot' the contact-point will fail to operate the pump. Again, the eiective stroke o' the contactpoiut e4 may be varied by changing the position of the fulcrum-stud t', upon which the rock-lever E is mounted, with relation to the center of the cam C by means of the lever J. If the stud is thrown over toward the cam C', the thrust of the latter will depress the contact-point e4 to a greater extent, and thereby cause an increased feed of oil, whereas if, on the contrary, the stud is moved by the lever J in. the opposite direction the contact-point will have less eiective thrust and less oil will be injected into the ignitionchamber. Consequently if the maximum degree of feed and speed is required the lever Jis drawn over to the fullest extent and the lever P is adjusted to hold the roller p out of contact with the roller m2, as shown in the drawings, under which conditions the maximum stroke and feed will be attained.

If the speed attained exceeds a certainlimit, the governor-segment T will be thrown out by centrifugal force until it comes in contact with the roller m2 at each rotation, thereby retracting the controlling-slide G more or less and modifying the elective stroke of the contact-point e4 until nally if the speed attained is excessive the governor-segment Will protrude sufficiently to retract the controlling-slide G until the recess g is brought under the contact-point e4 and the pump will cease to act. The same result may be attained independently and at any speed of running by means of the lever P acting through its rollerp against the roller on the lever M to rock the latter and retract the controlling-slide G more or less. In this connection it is to be noted that we do not conine ourselves to the use of rollers upon the levers, since they may obviously be omitted without materially affecting the operation of the mechanism.

In Fig. 3 the parts are shown as set to throw the pump out of action by means of the lever J, which is thrown back Aso far to carry the pivotal stud It' forward the distance necessary to bring the contact-point ovell the notch g in the controlling-slide G, and thereby renderthe thrustofsaid contact-pointineective.

In Fig. 1 the lever P is shown as brought so far forward as to retract the controllingslide g suiiciently to bring the notch g past the path of the contact-point e, so that the latter will strike the controlling-slide beyond said notch g, While the roller m2 is withdrawn beyond the reach ot` the governor-segment T upon the iiy-Wheel, thus admitting of the engine running to the full limit of its capacity.

By our improved construction and arrangement of parts we are enabled to vary and coutrol the speed of the engine with accuracy and convenience. Our controlling apparatus may be set to run automatically or may be operated directly by hand, or a modification of both methods may be adopted. 1

It is to be understood that by shifting the fulcrum of the lever E inward or outward the time of the feed may be changed within certain limits as related to the stroke of the pis- IOO IIO

ton as may be found most expedient in running the engine.
